Egypt launches strikes in Libya after Minya attack

Egyptian air force planes have carried out six strikes directed at camps near Derna in Libya, where armed men responsible for a deadly attack on Christians are believed to have trained, Egyptian military sources say.

Egyptian President Abdel Fattah el-Sisi announced on Friday that he had directed strikes against what he called "terrorist camps", declaring in a televised address that states that sponsored terrorism would be punished.

"Egypt will never hesitate to strike terror camps anywhere ... if it plans attacking Egypt whether inside or outside the country," Sisi said.

Earlier on Friday, at least 28 Coptic Christians were killed and dozens more wounded by armed men who attacked them while they were travelling to a monastery in Egypt's Minya province.
